Who needs the ACLs and static NAT?

I came apon a job whose network layout is kind of tricky. Here is the skinny:
2 routers (both 1721s). One is SBCs and it plugs into the internet on WIC interface. Nic interface plugs into a PIX 506E Firewall. The firewall does the PAT. The other eth port on the firewall plugs into the switch. The other router's WIC card plugs into the franchise intranet, and the NIC plugs into the switch.
All the PCs, servers, etc have the default gateway set to the ethernet interface of the franchise 1721. That router looks at the destination address and decides if it needs to go out it's WIC (if the dest. address is on the corporate intranet's subnet) or if it needs to go out to the internet (through the firewall and out the other router).
Now heres what I am trying to accomplish:
The customer wants to be able to telnet into one machine in the private network from her house.
Obviously, I need an ACL on the SBC router because thats where the request is comming from. I also have set up static NAT on the router from a public IP (in our valid range that SBC provides) and the private IP of the machine that she wants to access.
Currently, it is not working. I thought it had something to do with the other router so I started contacting the network engineers at the franchise office to get them to open up their router to allow telnet.
I now think however, that the reason it is not working is I have the static NAT on the wrong device!!
Shouldn't it be on the firewall, because the SBC router doesn't know anything about those private addresses (the PAT happens on the firewall).
Is my hunch right? Can you please advise me on what devices will needs changes in their ACLs and which device(s) will need static NAT mapping? I don't want to open any thing I don't have to. Thanks!!

I just came from the clients office. I am a little lost here. I am quite nifty at the CLI of a router or a switch, but every other firewall I have dealt with (Sonicwall, Watchgaurd, etc) has had a web based GUI. I am new in the field and have never configured a PIX before.
Here's what I have right now:
SBC router is configured to allow Telnet traffic in.
The PIX 506E has PAT configured on it. I tried setting up static NAT with no luck on the firewall. Attached is my running config. Perhaps you could instruct me on a some commands I can throw at this box to make this whole mess work!!
Let 207.184.18.10 be the address of the internal machine we want to access and SERVER.PUBLIC.IP be the public address we should point our telnet client to get in.

A 15" mid-2009 MBP RAM specifications are: 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM.
As has been pointed out, OWC is an excellent source for Mac compatible RAM. Crucial is another first rate source for Mac RAM. RAM from either vendor will work just as well as any purchased from Apple with the bonus of being less expensive and having a lifetime guarantee.

MS NLB with ASA and Static NAT from PUP to NLB IP

Hi all,
I am trying to get MS NLB up and running. It is almost all working. Below is my physical setup.
ASA 5510 > Cat 3750X >2x ESXi 5.1 Hosts > vSwitch > Windows 2012 NLB Guest VMs.
I have two VMs runing on two different ESXi hosts. They have two vNICs. One for managment and one for inside puplic subnet. The inside puplic subnet NICs are in the NLB cluster. The inside public subnet is NATed on the ASA to a outide public IP.
192.168.0.50 is the 1st VM
192.168.0.51 is the 2nd VM
192.168.0.52 is the cluster IP for heartbeat
192.168.0.53 is the cluster IP for NLB traffic.
0100.5e7f.0035 is the cluster MAC.
The NLB cluster is using MULTICAST
I have read the doumentation for both the ASA and CAT switch for adding a static ARP using the NLB IP and NLB MAC.
For the ASA I found
http://www.cisco.com/en/US/docs/security/asa/asa84/asdm64/configuration_guide/mode_fw.html#wp1226249
ASDM
Configuration > Device Management > Advanced > ARP > ARP Static Table
I was able to add my stic ARP just fine.
However, the next step was to enable ARP inspection.
Configuration > Device Management > Advanced > ARP > ARP Inspection
My ASDM does not list ARP Inspection, only has the ARP Static Table area. Not sure about this.
For the CAT Switch I found
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a07203.shtml
I added the both the ARP and Static MAC. For the static MAC I used the VLAN ID of the inside public subnet and the interfaces connected to both ESXi hosts.
On the ASA I added a static NAT for my outside Public IP to my inside pupblic NLB IP and vise versa. I then added a DNS entry for our domain to point to the outside public IP. I also added it to the public servers section allowing all IP traffic testing puproses.
At any rate the MS NLB is working ok. I can ping both the Public IP and the Inside NLB IP just fine from the outside. (I can ping the inside NLB IP becuase I'm on a VPN with access to my inside subnets) The problem is when I go to access a webpade from my NLB servers using the DNS or the Public IP I get a "This Page Can't Be Displyed" messgae. Now while on the VPN if I use the same URL but insied use the NLB IP and not the Public IP it works fine.
So I think there is soemthing wrong with the NATing of the Public to NLB IP even tho I can ping it fine. Below is my ASA Config. I have bolded the parts of Interest.
Result of the command: "show run"

Any help would be great! I think the issue is in teh NAT as I am able to access NLB IP from the outside and could not do that before adding the Static ARP stuff.
Thanks,
Chris

Also If I change to NAT from the public IP to the NLB IP to use either one of the phsyical IPs of the NLB cluster (192.168.0.50 or 51) it works fine when using the public IP. So it's definatly an issue when NATing the VIP of NLB cluster.

Dynamic PAT and Static NAT issue ASA 5515

Hi All,
Recently we migrated our network to ASA 5515, since we had configured nat pool overload on our existing router the users are able to translated their ip's outside. Right now my issue was when I use the existing NAT configured to our router into firewall, it seems that the translation was not successful actually I used Dynamic NAT. When I use the Dynamic PAT(Hide) all users are able to translated to the said public IP's. I know that PAT is Port address translation but when I use static nat for specific server. The Static NAT was not able to translated. Can anyone explain if there's any conflict whit PAT to Static NAT? I appriciate their response. Thanks!
- Bhal

Hi,
I would have to guess that you Dynamic PAT was perhaps configured as a Section 1 rule and Static NAT configured as Section 2 rule which would mean that the Dynamic PAT rule would always override the Static NAT for the said host.
The very basic configured for Static NAT and Default PAT I would do in the following way
object network STATIC
host
nat (inside,outside) static dns
object-group network DEFAULT-PAT-SOURCE
network-object
nat (inside,outside) after-auto source dynamic DEFAULT-PAT-SOURCE interface
The Static NAT would be configured as Network Object NAT (Section 2) and the Default PAT would be configured with Twice NAT / Manual NAT (after-auto specifies it as Section 3 rule)
This might sound confusing. Though it would be easier to say what the problem is if we saw the actual NAT configuration. Though I gave the reason that I think is probably one of the most likely reasons if there is some conflict with the 2 NAT rules
You can also check out a NAT document I made regarding the new NAT configuration format and its operation.

I just got my MIDI to USB cable, fired up Garageband. I clicked the basic lessons, tried Play. But the lesson guy is playing. I'm the one who needs the practice, not him. Please help. I don't know what I'm doing.

G35Guy:
Well, if that's the case, you must have a different finish on yours than I have on mine. Either that or you are extrordinarily careful when using it. Mine literally scratches when using a microfibre cloth. I would really like to know whether yours is somehow different. It would really piss me of if some people got a good quality exterior that doesn't scratch and some of us got the opposite. Did you try holding your player under a light to see if there is anything. You may just be looking at it in bad lighting. I find it hard to believe, unless your unit has a different type of plastic cover, that it hasn't received any type of scratches. Can you take a picture of it's It probably seems as though I don't believe you. That's not the case. Its just that I was so careful not to scratch it last night and it got scratched anyway. I have read of similar experiences by others who have the Vision:M as well.
I wish I could return mine and get a different color, it really upsets me that a $300 item that is meant to be hand held and used heavily scratches this easily!! If anyone from creative is reading this, I would like to know what you plan to do about it! I didn't pay all of that money to have this player look like Sh*t when I am only using it the way it was intended and am being very careful at that!

You can NOT do so. Only the owner of the account used to lock the phone can remove it. Instructions for how to do so can be found within or linked from within the document I already linked to.
Activation lock is an anti-theft feature designed to make the device useless to anyone other than the rightful owner.
If your friend refuses to give your money back and can not or will not remove the activation lock, there is a fair possibility that the phone was not theirs to sell in the first place.

Need the complete and correct way to reset Safari 5.1 the reason being is that 1. Even with the fix for .pdf's opening in Sarfai, they still don't and I have local copy of a html file that I use to access my most frequent sites and it refuses to open when Safari loads.
I need to know what to save so that I can reinstall it after the reset. I don't want to lose my cookies and passwords that I have saved.

Well I went back to one of my old discussions from a few months ago and found the right way to reset Safari but also dicovered that the file that my other older Mac had the same problem with, were I could'nt load a .pdf file into Safari as well as play video files, like the one that Apple posted of the Stve Job's tribute yesterday.QuickTime would'nt load so this morning got my act together and took each file that I thought might be corrupt out till I found the one that was, having to restart Safari and shut it down.
the file in the
Home/Library/Preferences>com.apple.Safari.plist was the culprit. I am now trying to find a way to see how one can tell if this file is corrupt before backing it up, since "plists" are not a file to mess with.
I hate resetting Safari since it destroys a bunch of files that one builds up over a long period of time, and hate to destroy all that work just because of one file. Hopefully if someone reads this they can find a way of having Safari back it up on a on going basis but making sure it is'nt corrupt in the process.

How to fiter packet in router exept the acl and firewall?

Subject is intact.
I found something interesting while trying to perform a process.
To be filtered by the ICMP protocol, where the ACL and Firewall, was that you should not use it.
But no matter how these ideas to Google, there was no answer to this.
Please share reference about this or more keywords, and your knowledge.

you are not clear on what you are trying to do..
You want to block all icmp without using access-lists?
I think an intrusion prevention system is a very expensive solution for this..
technically any device that can drop traffic is a firewall. So I don't see much other option for you. You could use a linux box running ip tables to do the same thing however that is still a firewall..

Command to see host and static nat for the same object together

I have researched this but cannot find an answer. ASA running version 8.5.
When you create the config using object NAT you enter the commands as follows
object network <object name>
   host x.x.x.x
   nat (inside,outside) static y.y.y.y
When the config is displayed it separates the host and nat commands in two different sections of the config as follows
object network <object name>
   host x.x.x.x
object network <object name>
   nat (inside,outside) static y.y.y.y
Is there a command that will display it all together (like it was typed in)? Show NAT is something like what I am after but without all of the extra info such as translate_hits, untranslate_hits etc. I need this information but cleaning up the output of a show nat is going to be tough.
Any suggestions?
Thanks.

Sorry, show nat detail is what I meant in the original post in place of show nat.   Show nat detail still has all of the extra info I was trying to avoid. Guess I will be editing a text file.
Thanks for the reply.

Who needs the JavaFX runtime redistributable? Please "Stand up and shout!"

With the 1.2 release JavaFX gains more momentum and more attractivity. Also for the "classic" desktop application sector. It has the ability to give Java apps all the eye candy and smoothness in operation that many end-users pretend/believe "Java does not have".
My only problem (as a developer and ISV!) is: I cannot build and sell applications for my customers with JavaFX!
... at least not in the way most of my customers would prefer:
- get the software as one single package,
- put it in/on the PC
- and USE it. Period.
There are many (very many!!!) customers (end-users!) who easily get very confused by:
- having to install "something called JRE"(1) on their box
- having to go to a certain website to get that JRE from
- or, beeing confronted with the web start screens and security warnings.
So, I would say, for an ISV distribution as a single package that starts "out of the box" is maybe even more important than the rather "advanced" or "sophisticated" webstart. Actually, for many customers who do not have a technical background, beeing confronted with the mentioned technical details quickly becomes a real show-stopper. Sorry, but that's the way many people work and think.
That's not good for me. That's not good for all the other ISVs. And that's not good for Java and Sun, either, I think.
And, as an entrepreneur, I would not like falling into what in German would be called "betting on the wrong horse".
But, if I understand the license correctly, that is exactly what I cannot do: Bundle my applications with a JRE & JavaFX runtime, just as I would be allowed to do with the JRE only. So there is no way of an one-package offline distribution and installation. And thus no way to reach a significant amount of users - and customers!
So, my questions in short are:
1) Is there someone at the forum, who shares my problems or fears?
2) Is there someone from Sun at the forum who could tell me something about what to do with JavaFX in that case? Is there something I have forgotten, or is there simply no way. Or are there future plannings on changing the license in a less restrictive way? If so: what is the schedule and what could the changes look like.
Best regards,
Robert
(1) Please don't get my irony wrong - I just frequently meet end-users who do not know much or even anything about Java or an JRE - sad but true ...

About 1): Yes, there are several questions about licensing and being able to distribute JavaFX applications offline, on computers not connected to Internet, among other requirements.
I would say your requirement are reasonable. I make for my work an install program deploying a JRE along a complete Java application, and for the user, he runs the application like any Windows application, no need to know it is Java based. That's nice and user friendly.

ACE and static NAT

Hello
I had pix+CSM on 6500. I've changed it to new ACE module on 6500.
I've made loadbalancing which was done on CSM. Now i wanted to connect dmz which was connected to pix and make static DNAT.
I used configuration guide/examples from: http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/security/guide/nat.html
I need to make static DNAT, but i can't figure how it works. There are many errors in this document including incorrect (old?) syntax (for example: nat static 192.0.0.0 255.0.0.0 80 vlan 101)
I analyzed three examples at the and of this document. My questions:
1. how do i choose if it's source or destination NAT ?
2. do i always apply service-policy to vlan interface which receives packets which should be natted ?
3. What is class-map(it's ACL) choosing ? Incoming traffic which destination address should be changed ?
4. is in command: "nat static A netmask netmaskA vlan B" A is outside ip address before translation to inside address ?
5. Could anybody give me a simple example of static DNAT ? (or any links?)
Thanx

Destination nat is equivalent to loadbalancing to one server.
I would therefore configure a vip being the inbound destination address, and a rserver which would be the outbound nated destination ip address.
Then create a policy-map to link the 2 together and apply the policy-map to the incoming vlan, or you can apply it globally.
For the reverse connections, where you then need to nat the source ip back to the 'VIP' you use the static nat config that you have found in the document.
By the way, I don't see anything wrong with it.
Those commands are in A1 and also the new A2 release.
ACE is really a loadbalancer with some firewall features and not the opposite.
This is why pure nating functions are not straightfoward to configure.

Using both Dynamic and Static NAT with two Different Internet facing Subnets

We have two Class C Public Address subnets. We started with Subnet (A) and have many of our Internet accessible devices on it. It is running on a Cisco PIX 515R. We bought a new ASA 5510 8.3(2) and started Migrating the Users and new servers to it so I started with our second Class C Subnet (B). Later on down the road I found out that if the Firewalls Default Gateway is is set to a (B) Interface subnet, then the servers that are statically mapped to a (A) Address will have a (B) address when they communicate out to the internet. So they are receiving packets on their (A) Address, though replying to them with a (B) address.
It was mentioned that I should be able to combine static and dynamic NAT mapping to allow devices behind the firewall to have a fixed external Address when communicating outbound as well as inbound.
So For instance I want the Following: when the Internal Replies I want the reply to come from the mapped IP, not a IP from the Dynamic Pool.
Public IP: 192.168.1.100/24

When I set this up my serverB shows a Public IP of something in the 192-168-1-NAT-POOL Not 192.168.5.101
Any Suggestions?
Thanks!

Not sure why I have Multiple Entries. )-: I did think it was Odd. I think it might be because I looking at examples of the new and old styles of NAT.
We have a Single ISP, though have 2 separate non-Contiguous Class C Addresses from them. We host some Servers on one subnet and some on the other.
I'm looking for a way to use both Subnets on the same ASA.
The Connection to the net looks like this:
Internet -> Edge Router Layer3 VLAN Switch
GE0/1.2 - 192.168.1.1 VLAN Tagged --> GE0 - VLAN Tagged
GE0/1.2 - 192.168.5.1 VLAN Tagged -^
Layer3 VLAN Switch Firewall
GE1 192.168.1.0/24 Untagged -> ASA Outside-1
GE2 192.168.5.0/24 Untagged -> ASA Outside-5
Firewall
ASA inside 10.0.0.0/16 -> Switch -> 10.0.0.100
Hope that helps clarify.
I could try to post some sanitized Configs of my PIX and ASA if needed. But the end result I'm trying to do is have the ASA do NAT for multiple Public Subnets.

Need help setting up static NAT to internal server

One of my internal servers requires it to be available to the internet I am having a hard time allowing it to be NATed through my Ciscc 2801 router. It seems as though im missing something small. From what I can gather it seems as though its as issue with ACL, but im not sure. I have ran the following command: ip nat inside source static tcp 192.168.5.1 ***WAN IP Address*** 8443 extendable Then I tried to add it to the ACL
via this command: access-list 150 permit tcp any host ***WAN IP Address*** eq 8443
Here is a copy of my config. Please advise. Thanks.

If you are planning to use the fa0/1 interface IP itself then the configuration would be:
ip nat inside source static tcp 172.19.3.133 8443 interface fa0/1 8443 extendable
Assuming that you would like to port forward TCP/8443.
Then the ACL should be written:
ip access-list extended 102
2 permit tcp any host eq 8443

Who needs the ACLs and static NAT?
